[jboss-dev-forums] [Design of JBoss Portal] - Re: portal clustering problem when using optimistic locking

Relax to R_C. See http://lists.jboss.org/pipermail/jbosscache-dev/2008-July/002401.html for a full discussion of this.

Re: increasing scalability, the work Galder and I are doing on JBCLUSTER-206 should help there.  Basically eliminating cluster-wide messages for the most common cache write operation. Once that is in, there should only be message traffic for new entities that are created and updates to existing entities. And if there are lots of those, the entity type is probably not a good choice for caching anyway.

Do you cache queries?  If not, try INVALIDATION_SYNC and see how that improves things.
